Amazing Flash Combustion Wood Heating… Seeing is Believing!

Flash combustion results when air suddenly finds hot smoke. If you disobey a fireman’s warning to keep a hot door shut, the air will rush into the room filled with hot smoke, and flash combust. The ‘air tight’ & ‘catalytic’ wood stoves are virtually extinct because they waste potent smoke fuel. This is the era of the ‘flash combustion’ stove. With seasoned pine, customers report a clean chimney despite burning sappy wood such as pine. With pine now an acceptable wood, heating can be near free. Pine logs and pallet wood are often there for the taking. This is wood others often reject in the common wood stove. Pine is rejected mainly because of the rapid creosote smoke build up. Chimney fires and chimney cleanings were the costly byproduct of burning pine.

However, the flash combustion of smoke consumes it as a fuel before it leaves the stove, and does so providing a beautiful flame display viewable through the stay clean glass. Furthermore, half the wood is consumed when the smoke fuel is burned! This means not only half the cost of older air tight stoves, but also half the work and double the burn duration. Savings from nearly eliminating the oil/electric/gas bills soon pay for the stove. At $250 for cord wood, it is the oil heating cost equivalent of 45 cents a gallon.

With a steel unibody stove, equipped with an over built door, stainless steel and high density refractory internal components, such as those made by ‘Lennox’, the result is dependable low end control. In the past, ‘air tight’ stoves would soon leak, and this excess air intake led to too much heat. This is why stove pipe dampers were always installed to restrict air flow when the stove could not. Stove pipe dampers are no longer allowed by code in most applications, so today’s leak prone stoves should be avoided. Another reason to avoid these stoves is that a hairline leak causes a catastrophic three fold loss in the stoves’ overall value. This is one of many eye opening demonstrations provided in an educational showroom in Rhode Island, called, “Fireside Stove Shoppe”. This must be seen to be understood.

Flash combustion triples the value of an air tight stove. All models today must prove, in the UL lab, that they are capable of this technology in order to be approved for sale. However, most lose this ability after a few inevitable red hot over fires. With low heat control, and the extreme long burn times of a large flash combustion stove, homes experience near even heating of the far reaches of the home. It does this by allowing heat to spread 24/7. One brand excels in this area. It is the ‘Country’ stove line by ‘Lennox’. This unheard of 24/7 burning leads to even temperatures, enough so to keep the furnace off. 24/7 burning is now feasible because it is now half the work, and much more rewarding, due to half the wood cost and stunning 24/7 fire views. Most customers report, to their surprise, the furnace stays mostly off, and the stove pays for itself in savings the first year or two. All of today’s new stove brochures promise essentially the same performance from the UL testing of the new stove, but most revert to behaving like the stoves of the past, at one third the value, and are not easily repaired.

Here’s why: All cast iron stoves have non-metal seams and poor quality door components. Most of these are the trusted brands of the past. These faults were tolerable then, but not now with flash combustion technology. Then, a burnt out seam meant just over firing as smoke could not be burned to double the efficiency anyway. It just meant more stove pipe damper use to slow the burn. Leaks were not a big loss back then. Repair was possible for about $600. That’s not the case with today’s new cast iron stoves. Now, it is cost prohibitive due to triple the parts, thus triple the labor. Add this cost to the uninstall, re-install, and shipping both ways and repair cost is far more than it’s worth. The warranty is worthless since you over fired it. The result is a total loss!

Unlike the past, leaks now mean a big loss in efficiency, heat control, & burn time. Furthermore, wood handling, ash removal, and chimney cleanings greatly increase. When leaks are not feasible to repair, you’ve lost your investment. Buyer beware. Flash combustion changes everything. For questions or feedback, please write John Debar at JohnDebar(at)
